Monitor car tire's pressure and temperature in real time.
Automatic sound and flash alarm six seconds after abnormal phenomenon appears, such as too high or too low  tire's pressure or leakage.
Automatic sound and flash alarm six seconds after tire’s temperature becomes too high (exceed 75°C)
Temperature Measure Precision:±3°C
The tire's pressure monitoring criterion can be customized.
The waterproof and dustproof sensor can be used under awful condition.
Normal life-span of sensor:over 5 years
Pressure measurement range: 0-65psi
Pressure Measure Precision: ±1.45psi
Sensor is designed as a separate fitting. It can be fixed on the valve, no needing to disassembly the tire when mounting it.
User can learn to displace the sensor easily, no needing to mount it in procedures.
Guard against theft and alarm system is available for sensor.
Suitable for passenger cars, can monitor four wheel-tires simultaneously.
